Abstract

This article contains a report on the experiences of the supervised training of Natural Sciences Course at the Pará State University. The study had the training field, a class elementary education in public schools of the city of Marabá / PA. The objective of the research was to propose an experiment with low-cost materials to assist in the teaching and learning process of optical content, which is the branch of physics responsible for the study of the phenomena associated with light. The methodology was divided into three stages: it was first carried out a survey of students prior knowledge about the optical content and planning of the introductory class; the second time was the implementation of the introductory class on the content and application of questionnaire; ending with the execution of the experimentation in the classroom and the same questionnaire applied to comparative analysis of data collected before and after the methodological intervention. The good development of students presented the proposal showed the experimental efficiency "total reflection and optical fiber" in the understanding of the subject on optics. What enabled the students a meaningful education, taking into account that he, the student, is the builder and owner of ideas, in addition to contributing to the construction of scientific knowledge.
